Which specific anthocyanin noted for its biological activity is abundant in purple tomato skin?
Answer
Nasunin
Within the complex chemistry of purple tomatoes, specific anthocyanins have been identified as particularly active contributors to the fruit's health profile. Among these, nasunin is specifically highlighted in scientific discussions for its noted biological activity. Nasunin is a type of anthocyanin that is found to be abundant within the skin of the purple tomato. While the entire spectrum of anthocyanins contributes benefits, nasunin represents a measurable chemical marker associated with the high antioxidant capacity being discussed. Identifying specific compounds like nasunin allows researchers and informed consumers to better assess the functional dietary value beyond just the general category of 'anthocyanins'.
